Basilosaurus is thought to have been one of the largest animals of the Paleogene, with the type species B. cetoides measuring around 17–20 metres (56–66 ft) long and weighing up to 15 metric tons (17 short tons). It was the top predator of its environment in the shallows of the inland sea, preying on sharks, large fish and other marine mammals.

Perucetus is the largest Eocene whale, with length estimates varying from 15–16 meters (49–52 ft) to 17–20 meters (56–66 ft).
